WEATHERSTRIP.

Specification of Letters Patent.

Patented Aug. 6, 1912.

Application led May 3, 1910. Serial No. 559,051.

To all whom it may concern:

Be it known that I, CHARLES E. ALDRED. a cit-izen of the United States` residing at Cairo, in the county of Alexander and State of Illinois, have invented new and useful.

Improvements in Teather-Strips, of which the following is a specification.

This invent-ion relates to weather strips and particularly to that type which are adaptable for outside doors or French Windows.

The object of the invention is the provision of means for automatically projecting a strip into engagement with the frame. of the door or window or into engagement with its sill when such door or window is closed and to automatically retract L said strip when the door is opened.

Further objects of the invention will appear as the specific description which follows is read in connection with the accompanying drawings which form a part of this application, and in which Figure 1 is a broken elevation of the device attached to the door. Fig. 2 is an inside elevation of the device removed from the door. Fig. 3 is a transverse section taken on the line 3--3 of Fig. 2.

Referring more especially to the drawing. l represents the door or window to which the device is attached, and 2 represents the frame of said. door or window. Secured to the bottom edge of the door or window a. guard strip 3 which is preferably constructed of sheet metal of suitable gage. This guard strip extends from either side of the door across the bottom and engages the door or window at its top.

. Rigidly secured to the inner side v"of the guard strip adjacent each end thereof are suitable .guiding ribs 4 which have T-heads 5 and are apertured as at 6 to receive the operating rod 7 which is slidably mounted therein. This operating rod projects beyond the end of the strip and has secured thereupon an elongated nut 8 which may be adjusted to secure a proper contact with the door frame and to cause the operating rod 7 to travel a proper distance to engage the sill or frame. A spiral spring surrounds the rod between an adjustable collar 9 and one of the Guiding strips 10 so as to normally retract t 1e rod and keep it in position whereby the nut. will engage the frame.

Pivotally mounted on the guard strip intermediate the guiding ribs are a. pair of bell crank levers 11 having their longer arms pivotallv connected with the operat` 4ing rod 7. Their short arms are beveled oil' as at 12 to present a cam face which rides upon the inside edge of the reciprocating strip 13. This strip is slotted so as to receive the guiding ribs and be guidedthereb v in its movement and on its outer edge is provided with a. sill engaging felt or rubber strip 14. When the' rod is moved by its engagement with the frame, the bell crank levers engage the inner end of the strip 13, and force it downwardly so as lto bring the strip 14 into engagement. with the sill or frame.

In order to retract the strip automatically with the opening of the door or-window, -I secure to the inner edge of the strip screw eyes 15 and from each screw eye there is led a flexible connecting device such as a cord or chain 16 to connection with the rod. 7. These connecting devices travel over suitable pulleys 17 which are revolubly mounted upon stub shafts 18 projecting from the inner face of the guard strip. From the above, it will be seen, that when the rod 7 is moved to normal position by the spring, the flexible connectors will cause the strip 13 to travel with the movement of the short legs of the bell crank levers 11 and be in continuous engagement therewith.

Having thus described the invention, what is claimed is In a device of the class described, the combination with a door, of a guard strip mounted thereon, guiding members secured to the inner side of said strip, a weather strip slidably mounted bet-Ween the doory and the guard strip and having slots to receive said guiding members, means carried by the guiding members to prevent lateral displacement of the weather strip, bell crank levers pivoted to the guard strip and having cam ends 12 freely engaging said weather strip, and an operating rod slidably mounted in the y guiding members andpivotallyoonnected to Suid pulleys,V substantially iras 'and fonthe the bel crank levers for operating the same, purposedescrib'ed. .y v 10 an adjustablcollar on the rod, a spring In testimony whereof I afx my signature v surrounding the operating rodkf between the in presence of two Witnesses.
